Download it from the official PHP resource: www.php.net PHP is easy to learn and runs efficiently on the server side

SQL can execute queries against a database SQL can retrieve data from a database SQL can insert records in a database SQL can update records in a database SQL can delete records from a database SQL can create new databases SQL can create new tables in a database SQL can create stored procedures in a database SQL can create views in a database SQL can set permissions on tables, procedures, and views

SQL is a Standard – BUT….

Although SQL is an ANSI (American National Standards Institute) standard, there are different versions of the SQL language.

However, to be compliant with the ANSI standard, they all support at least the major commands (such as SELECT, UPDATE, DELETE, INSERT, WHERE) in a similar manner.Note Note: Most of the SQL database programs also have their own proprietary extensions in addition to the SQL standard!Using SQL in Your Web Site

To build a web site that shows data from a database, you will need:

An RDBMS database program (i.e. MS Access, SQL Server, MySQL) To use a server-side scripting language, like PHP or ASP To use SQL to get the data you want To use HTML / CSS

RDBMS

RDBMS stands for Relational Database Management System.

RDBMS is the basis for SQL, and for all modern database systems such as MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access.

The data in RDBMS is stored in database objects called tables.

A table is a collection of related data entries and it consists of columns and rows.

CSS stands for Cascading Style Sheets CSS defines how HTML elements are to be displayed Styles were added to HTML 4.0 to solve a problem CSS saves a lot of work External Style Sheets are stored in CSS files

CSS Solved a Big Problem

HTML was NEVER intended to contain tags for formatting a document.

HTML was intended to define the content of a document, like:

<h1>This is a heading</h1>

<p>This is a paragraph.</p>

When tags like <font>, and color attributes were added to the HTML 3.2 specification, it started a nightmare for web developers. Development of large web sites, where fonts and color information were added to every single page, became a long and expensive process.

To solve this problem, the World Wide Web Consortium (W3C) created CSS.

In HTML 4.0, all formatting could (and should!) be removed from the HTML document, and stored in a separate CSS file.CSS Saves a Lot of Work!

The style definitions are normally saved in external .css files.

With an external style sheet file, you can change the look of an entire Web site by changing just one file!
